2020 BUICK ENCLAVE — Complaint #2018466
Open-data reference.
NHTSA Complaint about FUEL/PROPULSION SYSTEM filed August 21, 2024
NHTSA complaint #2018466 (ODI reference 11610097) concerns a 2020 BUICK ENCLAVE and was filed on August 21, 2024. The owner reports the failure occurred on August 20, 2024. The report was geocoded to Kentucky based on the filer's self-reported location. The affected component is categorized as fuel/propulsion system, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same BUICK ENCLAVE cohort independently describe similar fuel/propulsion system failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2020 BUICK ENCLAVE shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Vehicle would not go into park fortunately we were in a safe location to avoid a possible accident or injury. The vehicle has electronic transmission shifting. According to the dealership the park solenoid in the transmission valve body failed. This prevented us from putting the vehicle in park so it could safely be shut off. We were able to set electronic parking brake but ignition continued to remain on. Eventually had to disconnect the negative battery terminal. Had vehicle towed to dealership but could not release electric park bake or start vehicle with battery terminal reconnected. This is becoming a common problem with this transmission, so common that parts are on back order. This could be a very unsafe problem with this vehicle in the right circumstance. There should be a recall on this transmit that is used on multiple GM vehicles
